Mick Bourke has sent me the story of his great grandmother, Emily Jane Warburton. It was written as chapter 3 of his book on Bourke family history.
Emily emigrated to Australia in 1854, at the age of 1, along with her parents, Robert and Mary (nee Hulme). Her father was from Altrincham, her mother was from Timperley, and they married Bowdon St Mary in 1852. This is the same area where I grew up, but I haven’t found any links to my own family. Robert’s grandfather was John and his marriage record, at Bowdon in 1779, indicates he came from Warburton parish.
I have added Emily’s story to the Research/Papers page of the Warburton website, in the External Papers section.
Addendum: Mick tells me Emily had an unfortunate death. She died following an illegal abortion (of her 15th child). Her husband, Michael, was sentenced to two years imprisonment as having been a party to it.
